Portable cutting type pipe inner chamfering device

Abstract

The invention relates to a portable cutting type pipe inner chamfering device, belongs to the field of cutting tools, and aims to solve the problems that an existing chamfering device is low in cutting efficiency and poor in adaptability, and adopts the technical scheme that the portable cutting type pipe inner chamfering device comprises a positioning sleeve arranged at the end of a pipe to be machined in a sleeving manner, and a through hole is formed in the positioning sleeve; the knife rest is arranged in the positioning sleeve, and a blade is arranged on the knife rest; the blade and the inner wall of the positioning sleeve are arranged in a clearance mode, the edge of the blade faces the positioning sleeve, and the clearance between the blade and the positioning sleeve forms a space allowing the end of a to-be-machined pipe to be inserted. The tool rest is rotationally connected to the positioning sleeve through a rotating shaft, and the end of the rotating shaft protrudes out of the positioning sleeve and is used for being connected with a driving device. The blade cuts the end part of the pipe through the rotation of the tool rest, and the operation is convenient; the multiple blades are detachably connected to the tool rest, the cutting efficiency is high, and adjustment is convenient; and the gap between the blade and the positioning sleeve forms a space for inserting the end part of the to-be-processed pipe, so that the adaptability is good.

Description

technical field [0001] The invention belongs to the field of cutting tools, in particular to a portable cutting-type internal chamfering device for pipes. Background technique [0002] The special single standpipe system generally uses a reinforced inner spiral pipe as the drainage standpipe. The inner wall of this pipe has a number of protruding spiral ribs, so that when the sewage falls in the standpipe, it forms a spiral state along the inner wall. The ventilated "air core" reduces the pressure fluctuation in the pipe and increases the drainage flow. Since the wall thickness of the pipe is generally not equal to the step at the bottom of the pipe fitting socket, a step will be formed after connection, and the protruding ribs on the inner wall of the pipe will also protrude from the inner wall of the pipe fitting. Form interference, affect the ventilation effect, and have a certain impact on the drainage flow. Therefore, during the pipe installation process, it is necess...
